Yeah - this exp is a standard way tosolve this type of DEq equations. There are some kiknds of equations and for them You should use some standard solution (You need to remembere them or look into some math manual). The same like for Integrators from some more complicated functions - there are some standard ways to solve them, too.

About Laplace - yeah - You can see the same equation, something like:

**m+ k/s +d/(s^2)=0 => m*s^2+k*s+d=0**
with the same result like with this Aspirin's way, but Yeah - it needs much more theory to show and explain here.
